TYPEWRITING MACHINE.

Application flledMarch 23, 1922. Serial No. 546,040.

To all whom it may concern:

Be it known that I, GEORGE A. SEIB, a citizen of the United States, and resident of Ilion, inthe county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting and like machines and more particularly to tabulator mechanism therefor.

The main object of my present invent on is to provide a detachable stop which is 51mple to manufacture and efficient in use, and

which may be adjusted to any column determining position on a stop bar and convert an existing form of column selecting tabulator into a denominational selector by 1ts co-operation with the stop of my invention.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of arts, and combinations of devices, set forth in the following description and partlcularly pointed out in the appended claims.

In the drawings, wherein like reference characters designate corresponding parts in the different views,

Figure 1 is a fragmentary detail fore-andaft vertical sectional view showing a portion of a No. 10 Remington typewriting machine, embodying my invention.

Figure 2 is a fragmentary plan view of a portion of the same.

Figure 3 is a detail fragmentary rear view of the column stop bar. with the multiple sto of my invention mounted thereon.

igure 4 is an enlarged detail transverse sectional view of the same, taken on the line 4-4 of Fig. 3 and looking'in the direction of the arrows at said line.

Figure 5 is a detail top plan view showing the upper portion of the tabulator frame and parts carried thereby. I,

Figure 6 is an enlarged detail perspective view of the multiple stop of my invention.

The No. 10 Remington machine includes a column selector, with features somewhat like those shown in my Patents, Nos.

1,132,286 and 1,273,545 dated respectively Mch. 16, 1915, and July 23, 1918. I have shown my invention embodied in such a machine, and by the simple expedient of using the multiple stop of my present invention, may convert the column selector of that machine into a denominational selector, as will hereinafter more fully appear. In the accompanying drawin s I have shown only so much of the No. '10 emington machine as is necessary to arrive at an understanding of my invention in its embodiment therein.

The frame of the machine comprises a base 1, corner osts 2 and a top plate 3. The carriage 4, w ich supports a platen 5, is mounted to travel on anti-friction rollers 6 over the top plate in the usual manner under control of escapement mechanism, not shown. A tabulator frame 7 is detachably secured to the frame of the machine by screws 8 and 9, as in my said Patent No. 1,273,545. Upstanding tabulator-stop actuating levers 10 are fulcrumed on a pivot rod 11 supported'at its ends by lugs or arms 12 which project forward from the tabulator frame 7 The upper forwardlyextending end 13 of each lever 10 coacts with a plate-like stop 14, pivoted at one end on a vertically disposed pivot 14, The stops 14 thushave a superposed arrangement moving in parallel horizontal planes that extend transversely of the machine. These stops are provided with vertically aligned contacts 15; each stop being under control only of its associated actuating lever 10 and moving in a horizontal plane or path which differs from that of each of the other stops. In the present instance five stops 14 and five actuating levers therefor are shown, though the number employed is immaterial. Each actuating lever 10 coacts with a spring 16 which bears aton end' against a shoulder 17 on the tabulator frame,

' normal position after pressure on the associated tabulator key is released. Each stop 14 coacts with an independent spring 19 (see Fig. 5) by which it is returned from the projected position back to its normal position,

Each lever 10 is pivoted at 20 to a forwardly extending link 21 pivoted at its forward end, as at 22, to an angular lever 23. The levers 23 are maintained spaced apart and are pivoted on a fixed pivot rod 24 Y secured at its ends to the frame of the machine. A forwardly projecting finger 25 on each lever 23 extends through an open-.

ing in the stem 26 of a tabulator key 27. These keys may bear suitable indices 28', or they may-Ibe plain and suitable indices provided on a fixed flange 29 on the front plate 30 of the machine, as is now done in the No. 10 Remington machine. 0n the other hand, I prefer to provide numerical indices 1, 2", 3, 4 and 5 (indicated at 28) On the keys, reading progressively from left to right, and to provide on the face of the flange 29 denominational indices 31 opposite the respective keys 27. In the present instance l have shown a series of indices U, T, H and Th, reading in the order named from right to left, though a differentarrangement of denominational indices may be provided. The use of these two sets of indices 28 and 31 will hereinafter appear.

It will be understood that the depression of a tabulator key is effective to project the companion stop 14 into the path of a stop on the carriage and simultaneously release the carriage by carriage releasing means, not shown. In the No. 10 Remington machine the carriage is provided with arms 32 to which is fixed a toothed column stop bar 33 that carries a series (or a multiple of such series) of five individually adjustable column stops, the contact on each stop of the series traveling in a different path, and in a path which is coincident with the plane of one of the stops 14. It follows therefore that the depression of a key 27, which in said machine is a column selecting key, determines the columnar position of arrest of the carriage. By my present invention I contemplate employing, either in addition to or independently of the ordinary column stops, the multiple stop of my invention and which is shown in detail and detached in Fig. 6. This stop is designated as a whole by the reference numeral 34, and comprises a block of metal which constitutes the body portion of the stop, and is bifurcated to straddle the stop bar 33 and to be detachably fixed to and adjusted to difi'erent points along the bar. This block has bifurcated sheet metal plates 35 riveted at 36 to opposite sides thereof. The parallel edge portions 37 of each plate are received in spaces between teeth 38' on opposite sidesof the column stop bar 33 to hold the stop in its adjustedposition on the bar. A finger piece 39 may be provided on the block to facilitate its attachment to and detachment from the bar, and a spring pressed ball detent 40 may be employed to hold the stop block against accidental detachment from the bar. One of the rectangular sides of the block has a series of holes 41 drilled therein (see Fig. 7), the number of holes depending on the number of stops 14 employed in the machine, which is five in the present instance. These holes are arranged. in an inclined line or diagonally enemas across theface of the block. Each hole 41 receives the stem 42 of a' stop pin having an enlarged head 43 that projects from the face of the block towards the rear and in the eneral direction of the stops 14 when the lock is seated on the stop bar. The point of juncture where the enlarged head of each pin joins its stem, forms a shoulder 44 that is adapted to bear against the drilled face or body portion of the block and limit the extent to which each pin may be driven into its hole, and therefore insure that all of the pins will project from the face of the block a uniform distance. The holes 41 and the stems 42 of the pins are so shaped and proportioned that the stems when driven into their holes will be firmly held by a drive fit against removal, and the pins are thus securely fixed to the block.

From an inspection of Figs. 3 and 4, it will be seen that the enlarged heads of the pins have an overlapping arrangement whether viewed in the direction of the length of the stop bar or at right angles thereto, and form firm substantial contacts to receive the impact at each arrest of the carriage. It will be understood, moreover, that notwithstanding this overlapping arrangement of the heads of the pins the effective contact faces 45 thereof are in vertical parallel planes a letter space distance apart, and are cut by parallel horizontal planes each coincident with the plane of movement of one, and only one, of the selecting stops 14. It follows therefore that the vertically aligned contacts 15 on the column selecting stops 14 will coact with the pins on the stop-block 34 to denominationally select the position of arrest of the carriage.

It is in order to indicate the key to be actuated in both column and denominational selecting that the two sets of indices 28 and 31 are provided. When column selecting, with the use of the column stops ordinarily employed, the indices 28 will be used to select the first, second, third, fourth and fifth columns, depending on the particular key 27 which is actuated, and which keys are indicated by the corresponding numerals 1, 2, 377, 4: 577. To tionallyselect, the indices 31 are used. For example, to write .99 the operator should depress the decimal key indicated by the decimal mark After the tabulator key is released the operator may then print the decimal mark followed by the figures 99. Should the operator desire to write 9999.99 the key 27 forward of the index Th should be depressed and after the carriage is arrested the figures and the decimal mark may be Written in the order appearing above.

From the foregoing description it will be understood that by the very simple expeselector used for example in the No. 10 Remington machine, it maybe readily employed as a denominational selector.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting or like machine, the

combination of a carriage, a plurality of key-controlled individually-movable columnselecting stops movable in different parallel planes that extend transversely of themachine, a toothed stop bar carried by the carriage, a multiple stop block that straddles said bar and is adjustable to different points along the bar and engages between the teeth thereof, said stop block having a series of holes formed therein in an inclined line, the number of holes corresponding to the number of said key controlled stops, and a series of pins driven into said holes and firmly secured to said stop block.

2. A detachable adjustable tabulator stop for typewriting and like machines comprising a bifurcated stop block, having a series of holes drilled through one rectangular side thereof and in a diagonal line across the same, a series of shouldered pins driven into said holes a uniform distance with theirshoulders bearing against the body portion of the block and firmly secured against detachment therefrom by a drive-fit, the efl'ective faces of said plins having. different paralt e stopis in use and arlel paths when ranged coincident with parallel planes arranged a letter space interval apart and ex tending at right angles to said paths of movement, the head of each pin which projects from the body of the stop overlapping an adjacent pin as the stop is viewed in two directions at right angles to each other.

v 3. In a typewriting machine and a column selecting mechanism, means for using said column selecting mechanism as a denominational selector comprising an adjustably and detachably mounted stop block bifurcated to straddle a stop rod and formed with a series of, holes arranged in an inclined line, and a' apart.
